FAN.

SPECIFICATION forming part of Letters Patent No. 326,888, dated September 22, 1885,

Application filed June 20, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES M. SEYMOUR, a citizen of the United States, residing in Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Fan Attachments, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is to furnish a convenient means of supporting and starting and stopping a fan in an apartment when the driving-power is located beneath the floor, and when the fan is necessarily mounted up on a column. Such fans are located in such a variety of situations that a cord or belt is the most convenient means of transmitting motion to them from the motive power; and my invention isintended to furnish the means for stopping and starting such fans without throwing off or disengaging the driving-belt.

The invention consists in the combination, with a supporting-floor and a post or column secured in an upright position thereto in an apartment above the floor, of a vertical shaft supported in bearings upon said column, a rotary fan applied to its upper end, a cl utching mechani m applied to its lower end, means located in an apartment below the floor for rotating the driving part of the clutch continuously, a lever beneath the floor for operating the clutch, and a rod extended from the lever through the floor for operating the clutch.

In the drawings, Figure l is a side elevation of a column having a central rotating shaft with a fan at the top and a frictionclutch, shown in section, at the bottom; and Fig. 2 is a bottom plan of the foot of the column and the clutching mechanism.

Ais the floor of the apartment in which the fan is to be operated, and beneath which the driving-power is applied to the fan. B is the column; 0, a vertical shaft preferably concealed in the column, and having the fan D mounted upon its upper end. The hub D of the fan D is secured rigidly to the upper end of the shaft, and the latter is extended through the column and floor A to receive the required motion. The shaft has attached to it at the bottom a friction-disk, e, which may be rotated at the pleasure of the operator by pressing a rotating frictioirdi'iver. 0, against it. This driver is fitted to turn loosely upon the lower end of the shaft, and is rotated by a pulley, e", affixed to it, and by a driving-belt, f. The friction-disk or driver may be faced with leather, as shown at g, and is pressed upward against the disk 6 by a lever, h, which bears upon the center of a hub, f, formed on the pulley c outside of the end of the shaft. The lever is actuated from the apartment above by a rod, 2', and handle J. The rod is carried up through the floor, and the handle is pivoted to the column B,where a segment, K, and clamp-screw Z are provided to hold the handle fast in various positions.

The friction-driver 6 can be pressed against the disk 0 with any desired degree of force, and different degrees of speed may thus be imparted to the fan from a driver having a fixed velocity.

\Vith this construction it is obvious that the fan may be entirely stopped at any time by any one in the same apartment, or may be made to go faster or slower, and all by the use of the same driving mechanism.

The speed of the fan may also be regulated by extending the lever h in the opposite direction from its fulcrum and applying a weight, XV, thereto, as shown in dotted lines in the drawings. The weight can thus be adjusted upon the lever so that it will be only necessary to loosen the clamp-screw Z in order to set the fan in motion at the speed for which the clutching mechanism has been adjusted. The fan can be stopped when this construction is adopted by pressing the lever J downward, thus counteracting the weight W and pressing the driver 6 away from the disk 6. It will be seen that the essential principle of the invention is the combination of a supporting-column, a shaft provided with the fan at its upper end and at its lower end with the power-driver beneath the floor, and suitable clutch mechanism, whereby the fan may be stopped without throwing offthe driving-belt.

I have not claimed herein the combination of a belt-pulley and a fan-hub, both arranged upon the top of the column, with clutching mechanism to join them when desired, but have claimed the samein a separate patent the clutch continuously, a lever beneath the floor for operating the clutch, and a rod extended from the lever through" the floor for operating the lever, substantially as herein shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JAMES H. SEYMOUR.
